評(píng)論
導(dǎo)讀:芹菜主要病害有斑枯病、葉斑病、菌核病、根結(jié)線蟲病等;主要害蟲有蚜蟲、斑潛蠅、薊馬、甜菜夜蛾等。
【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 為指導(dǎo)各地開展芹菜綠色生產(chǎn),提高斑潛蠅、蚜蟲、根結(jié)線蟲病等病蟲害綠色防控技術(shù)應(yīng)用水平,保障芹菜生產(chǎn)安全和質(zhì)量安全,特制定本方案。
一、防控目標(biāo)
芹菜種植區(qū)主要病蟲害防治處置率達(dá)到90%以上,總體防控效果85%以上,危害損失率控制在10%以內(nèi)。
二、防控策略
貫徹“預(yù)防為主,綜合防治”的植保方針。通過協(xié)調(diào)應(yīng)用健康栽培、生物防治、理化誘控和科學(xué)用藥等技術(shù)措施,實(shí)現(xiàn)芹菜主要病蟲害的有效控制。
三、防控對(duì)象
芹菜主要病害有斑枯病、葉斑病、菌核病、根結(jié)線蟲病等;主要害蟲有蚜蟲、斑潛蠅、薊馬、甜菜夜蛾等。
四、防控措施
(一)加強(qiáng)監(jiān)測
懸掛黃板監(jiān)測蚜蟲、斑潛蠅等;懸掛藍(lán)板監(jiān)測薊馬;安裝性信息素誘捕器監(jiān)測甜菜夜蛾;人工調(diào)查病害發(fā)生情況。
(二)健康栽培
1.選用抗(耐)性品種。宜選用商品性好、適合當(dāng)?shù)胤N植的抗(耐)性品種。
2.輪作。不應(yīng)與香菜、胡蘿卜等傘形科蔬菜重茬,可與水稻、玉米等作物輪作。
3.清潔田園。及時(shí)清理殘株、敗葉,集中深埋或堆漚處理。
4.翻耕曬垡。播種前,深翻土壤30厘米,曬垡5~7天,在溝渠和保護(hù)地邊緣撒生石灰。
5.科學(xué)施肥。結(jié)合深耕,施足基肥,合理追肥。宜施用餅肥或充分腐熟的農(nóng)家肥。
6.控溫控濕,通風(fēng)透光。保護(hù)地芹菜,白天棚室溫度宜控制在15—20 ℃,高于25 ℃應(yīng)及時(shí)放風(fēng),降溫降濕,相對(duì)濕度控制在50—60%。夜間溫度不低于10 ℃,相對(duì)濕度不高于80%。
(三)高溫悶棚消毒
利用夏季高溫休閑時(shí)間,將粉碎的稻草或玉米秸稈500公斤/畝,豬糞、牛糞等未腐熟的有機(jī)肥4—5立方米/畝,氰氨化鈣70—80公斤/畝,均勻鋪撒在棚室內(nèi)的土壤表面。然后用
旋耕機(jī)深翻地25—40厘米,起壟后覆膜澆水同時(shí)封閉棚膜。保持高溫悶棚20—30天,處理結(jié)束后揭膜,旋耕土壤晾曬7—10天,使用微生物菌劑處理后即可種植。
(四)生物防治
1.施用微生物制劑。預(yù)防土傳病害,可在播種或定植前使用木霉菌、枯草芽孢桿菌等生物菌劑進(jìn)行土壤處理;對(duì)于根結(jié)線蟲病發(fā)生地塊,選用厚孢輪枝菌顆粒劑、淡紫擬青霉進(jìn)行土壤處理或者穴施,或殺線蟲芽孢桿菌B16進(jìn)行穴施或者撒施,或蘇云金桿菌HAN055隨水沖施或灌根,或蠟質(zhì)芽孢桿菌灌根;防治薊馬、蚜蟲、甜菜夜蛾,應(yīng)在害蟲發(fā)生初期或低齡幼蟲期,選用綠僵菌、球孢白僵菌等微生物藥劑;防治甜菜夜蛾,可選用甜菜夜蛾核型多角體病毒進(jìn)行防治。
2.利用天敵。初見害蟲時(shí)釋放天敵,利用食蚜癭蚊、瓢蟲、蚜繭蜂等防治蚜蟲,利用小花蝽、捕食螨等防治薊馬,釋放草蛉、蠋蝽等防治甜菜夜蛾等鱗翅目害蟲。
(五)理化誘控
在棚室門口和通風(fēng)口安裝40—60目防蟲網(wǎng);使用甜菜夜蛾性誘劑和誘捕器誘殺成蟲。
(六)科學(xué)用藥
防治蚜蟲,選用苦參堿、吡蟲啉、吡蚜酮、啶蟲脒、噻蟲嗪等藥劑;防治甜菜夜蛾,選用苦皮藤素等藥劑;防治斑枯病、葉斑病、菌核病等病害,選用咪鮮胺、苯醚甲環(huán)唑、吡唑醚菌酯、丙環(huán)唑、戊唑醇等藥劑。種植前可采取種子和土壤處理,苗期和生長期灌根、噴施等方式進(jìn)行施藥。輪換使用不同作用機(jī)制農(nóng)藥,并嚴(yán)格遵守用藥劑量、用藥方法、用藥次數(shù)和安全間隔期。
